The volume control puts an AC load on the detector causing distortion in the audio. The diode used has to be a germanium type or a hot carrier diode that has a low forward conduction voltage. The ...

The diode bias current is created by a transistor-based peak detector circuit driven off the main audio signal. But don’t just take our word for it, watch the video after the break.

The history of the diode is a fun one as it’s rife with ... he had a piece of metal connected to the positive end of the circuit and held near the filament. He found that an invisible current ...

From a primitive-diode beginning, it advanced to multi-function-detector integrated circuits (ICs). Diode rectifier circuits have been used for signal-level detection for almost a century.

The standard hardware requirements for sample-and-hold and peak detector circuits apply to D1, C1, and A2. C1 must be a high-quality capacitor, D1 must be a low-leakage diode, and the bias current ...

Following their improved diode design, the researchers created a highly efficient SD rectifier circuit ... computers and sophisticated quantum detectors used to search for dark matter.

This easy-to-construct circuit causes a standard LED bulb to glow when infrared is detected by an infrared photo-diode or phototransistor ... your newly constructed detector but don’t have ...
